tain Improvements in Machines for Coating' Articles with Parailin or othcr Coating Material, of which the following is a specificat-ion.

My invention is especially ada ted for, use in coating paper ottles or ot ier con tainers with paraiiin, and the object of my; invention is to so construct the machine that the bottle'will be completely coated with parailin in such a'manner that the paraiiin will be distributed evenly over the exposed surface of the bottle.

Another object is to parailin the corners of the bottle in order to close all exposed cavities. A bottle of this type is intended primarily for use as a container for mill: and othermatcrial which would deteriorate when contained in'a vessel that is not absolutely clean, and a bottle of this type is used once and then discarded.

In the accompanying drawings,-Figure 1, is a longitudinal sectional view of my improved machine for parafiining; paper bottles and other containers; Fig. 2, is an end view looking in the direction of the arrow, Fig. 1; Fi 3, is a pcrs ective view of one of the bottle carriers; 1g. 4, is a sectional view of one of the bottle carriers with the upper ends of the arms broken away; Fig. 5, is a perspective view of a portion of the knock-off arm.

A is a kettle containing the liquid parafiin; this kettle is surrounded by a casing A in which are steam pipes O, and Ipreferably place water between the main and the kettlc, forming a water ljacket; tie steam coils heating the water, w iich keeps the paraffin in proper 1i uid condition. 7

B is an enillcss belt, made up of side chains and cross bars, the chains pass around footwhcels D mounted on a shaft D adapted to bearin s carried by the frame of the kettle A. T ey'also pass around belt-wheels E mounted on a shaft E adapted to adjustable bearings onthe casing F. .Set screws 6 are used for the ur 'ose of remilating the tension of thebe t. he belt'also passes around large a rocketwheels G mounted on ashatt G. TllS sprocket wheelie practically an idler and is used for directing the return run of the belt in the proper path," so that the surplus parafiin from the bottles will drip directly into the kettle.

g, g, g are other idlers for the belt, and these may be increased or decreased according to the length of the belt. The casing l is mounted on the kettle and is open at one and f for the introduction of the bottles, and

is open at the opposite end f for the discharge of the coated bottles.

Mounted on the bars of the belt B are a series of carriers 6, each made as shown in Figs. 3 and 4 in the present instance having three arms I) with inturncd ortions clamped between two disks 1) and by a bolt 6. By this arrangement the arms I) can be moved toward and from each other to fit bottles of different diameters, these arms are bent toward the center of the carriers at their outer ends.

c are the bottles, ta ercd in form in the present instance, the ottom of the bottle sing at the narrow end.

An operator can stand in front of the machine andreadily force a bottle over the arms of the carrier, the arms having sufii cient spring in them to retain the bottle until it is forced off the arms b the knockofi device H consisting of a shart H havin arms h and projecting heads h arrange to strike the edge of the bottle between the arms 5 forcing it oil the arms and discharging it into a trough f open at the end, and the o erator takes the bottle from this trough. he knock-ell device is, in the present instance, actuated by hand and is controlled by a lever h towhich is attached a rod h, and this rod is provided with a suitable handle so that when the machine is at rest the operator can simply all the handle and discharge the bottle. in some instances the knock-off device may be actuated by the operator at the rear end of the machine by simply extending the handle to that end of the machine.

,1' refer to move the endless conveyer by hand so as to insure the proper placing of the bottles on the carriers, and the same operator that feeds the machine can 0 crate the belt, and in the present instance have shown a-lever N pivoted on a shaft D and provided. with a pawl a, which engages with a ratchet wheel 71.? secured to the shaft D so that on reciprocating the lever N the shaftbefrotated intermittently in one direction andv will move the belt so as to bringone "row of carriers into position in front of the opening" 1 at each movement of the lever. i

In order, toallow the aratlin to beabsorbcd by the paper of tie bottle, I preferably provide a steam coil C directly under the return run of the belt B, as indicated, and this coil may be connected separately or with the coil C, as shown by dotted lines. so that after the major portion ofthe paraffin has dripped'from the bottle, and if there is any small amount remaining within the bottle, it is all accumulated in the bottom and by applying the heat directly under the bottle, as shown, this surplus will,

be takcnup and absorbed by the bottle, so that by the time the bottle reaches the discharge point all the surplus parailin is taken up and'absorbed and a perfectly coated bottle is the" result.

It will be noticed in referring to Fig. 1, that the kettle is so shaped that the bottles travel close'to it and when the kettle is otherwise shaped guides are used so that it 'have' shown it"of such a width that ten bottles-can be" placed side by side, but the capacity of the machine will depend materially upon-the-numher ofbottles made. Y

\"Vhile I have shown a hand operated ma- .ehine, it will be understood that it may be operated by power with the use of any well known mechanism.

The operation of the machine is as follows: The machine is set in motion and heat/is applied, the operator stands in front of the machine. with a nest of bottles and takes one at a time from the nest and places it on the carrier, and when the carriers are filled the handle N is reci rocated, moving the bottles into the para a and bringing into position another set of carriers to be filled, and this operation is repeated.

It will be noticed that. two setsof bottles remain submer. ,ed in the parallin at each operation, one )ottle remaining in the para tin while two sets of carriers are being filled. This gives the paratlin suiiicient o portunity to coat the bottles and when he ottles are moved to the next position the are directly above the kettle and at SllCl an incline that thesurplus parallln within the bottles will drip out into the kettle. In the next three movements the bottleis turned to/ a vertical osition, yet always above the kettle, allowing the-surplus arafiin'suflicienttime to drip back into the et- 'tle,-and anyv paratfin remaining on the out- 'sideof the bottles will drip onto the bottom of the casin F and will be returned to the kettle over the inclined drainage apron f.

When the bottle is in an upright position it is close to the heating coils and an surplus parafiin that would remain within the )ottle is absorbed, due .to the heat of the coils, and the bottom of the bottle becomes thorou hl v coated and saturated with the parailiii, filling up any holes or cavities which may exist. When the bottle reaches the point directly above the opening 7" the knock-oil is actuated and the bottle is discharged into the trough f and the operator at that end of the machine can take the bottles, placing them again in nests of a given number, and pack them immediately in bags, or boxes, so that the bottles can be shipped to their destination with the least. amount of exposure to the air, as it is essential in the manufacture of bottles of this type to practically sterilize them and keep them closed until used.

I claim,-

1. The combination in a machine for coatin the interior. and exterior of bottles and otier articles of a kettle, an endless belt having a foot wheel above the kettle and a head wheel some distance from the kettle, a guide wheel around which the belt passes as it leaves-the foot wheel, fixed carriers on the belt arranged substantially at right angles tothe longitudinal line of the belt the uide wheel extending over a portion oi the toot .wheel so that the bottles will ,enter the liquid in a substantially horizontal position and as they are removed from the liquid they will be tipped a sufficient distance, due to the position of the guide wheel, to allow them to drain.

2. The combination in a machine for coatin the interior and exterior of bottles and char articles, of a kettle, an endless belt having a foot wheel directly above the hottle, a head wheel some distance from the kettle, uide wheels for directing the belt no in a su stantially vertical path, fixed carriers on the belt for holding the bottles to be dipped in a position substantially at right angles to the run of the belt, the guide wheel for the return run of the belt extending its over a ortion of the foot wheel so that as the bott es leave the li aid in the kettle they will be inclined to al ow a given quantity of' the liquid to drain from the interior after which they will assume a horizontal 120 position as they are carried by the belt to the head wheel so as to allow tie remaining liquid to settle in the bottom of the bottle to term a seal.

w 3. The combination in a machine for cost 3.25

of the kettle some distance from the foot wheel, a small guide wheel for the forward run of the conveyer and a large guide wheel for the return run of the conveyer, said conveyer being made up of two chains spaced apart with a series of cross bars extending from one chain to the other, a series of carriers mounted on each cross bar and arranged so as to hold the bottle or other article substantially at right angles to the. longitudinal line of the conveyer, a casing inclosing the horizontal portion of the conveyer, the small guide wheel being set back of a vertical line drawn from the foot wheel so that the bottles will be fed into the liquid and so that the liquid will gradually flow into the bottle, the large guide wheel overhanging the foot wheel so that the bottles will be slightly tilted to allow them to drip before assuming a vertical position, the remainder of the liquid in the bottle forming a seal in the bottom of the bottle as it accumulates while traveling in a horizontal position, with means for discharging the I bottle from the carrier at the end of the return run of the conveyer.

l 4. The combination, in a machine for coating the interior and exterior of bottles and I other articles, of a kettle, an endless belt having a foot wheel above the kettle and a head wheel some distance from the kettle,

l a guide wheel around which the belt passes.

as it leaves the foot wheel, fixed carriers I on the belt arranged substantially at right i angles to the longitudinal line of the belt,

the guide wheel extending over a portion of l the foot wheel so that the bottles will enter 1 the liquid and as they are removed from the l liquid will betipped a suflicient distance,

i due to the position of the guide-wheel, to

! allow them to drain.

* In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
